Req #42960 [Opn]: PHP messes up image submit button data

Edit report at https://bugs.php.net/bug.php?id=42960&edit=1 ID: 42960 Updated by: cmb@php.net Reported by: efbiaiinzinz at hotmail dot com Summary: PHP messes up image submit button data Status: Open Type: Feature/Change Request Package: *General Issues Operating System: * PHP Version: 5.2.4 Block user comment: N Private report: N New Comment: Regarding HTTP, there is nothing special with parameter names containing brackets or dots. Regarding HTML forms, for <input type="image" name="foo"> actually two parameters are sent (foo.x foo.y). PHP translates any dots in HTTP parameters to underscores, and treats bracketed parts as array indexes. However, it just ignores *any* trailing content after the last bracket pair. > Using the extra [] seems to be ok as workaround? I wouldn't rely on that. Maybe better don't use arrays for multiple images, but roll your own treatment. E.g. use names like smth_1, smth_2, etc., and scan for these array indexes (smth_1_x, etc.) Previous Comments: ------------------------------------------------------------------------ [2021-09-13 14:34:33] ddpm at liscovius dot de What the "living" standard says: https://html.spec.whatwg.org/multipage/input.html#image-button-state-(type=image) ------------------------------------------------------------------------ [2021-09-13 14:06:16] ddpm at liscovius dot de My previous comment shows a better example to understand the issue.
